skilled in the art to which it appertains to make and use the same.

My invention relates to dampers and damper operating mechanisms, and to furnace radiators.

It has previously been proposed to pro- .vide furnace radiators having detouring paths extending from the combustion cham her to the chimney flue, and in such constructions the cleaning-out door on the front part of the radiator usually lines with the fire door and the ash door, but due to the positioning of the furnace relative to obstructing walls such as the Wall of a coal bin and other obstructions, it sometimes becomes necessary to so swing the radiator around that the cleaning-out door will not line up with the front of the furnace.

It has been found desirable that the control of the damper should still be retained at a point in the front of the furnace, just as though the front of the radiator were arranged to coincide with the front of the furnace. In order to accomplish this, I control the damper in the short cut or di-' rect flue, through the medium of a gear mounted on the shaft of the damper, which shaft is vertically disposed, so that the gear lies in a horizontal plane on top of the radiator. I

At a point coincident with the vertical axis of the radiator, which axis is the central axis on which the radiator rotates, when its-front is shifted out of alignment with the front of the furnace, I mount a second gear wheel. This centrally located gear wheel meshes with the first gear mentioned. With this arrangement, I can retain the control of the damper in the front of the furnace, regardless of the position of the radiator, and as far as I am aware, I am the first one to obtain this result, and I am the first one to provide the means and of a diameter Renewed October 5, 1923.

above indicated for accomplishing this purpose.

Therefore, among vention, are the followmg'z the objects of my in- To provide a pivoted member centrally located with reference to the furnace, whereby the damper and the direct flue may be controlled from a given point, with respect to the foundation of the furnace, and regardless of the rotation of the cap or radiator of the furnace.

To provide details of improvements tending to increase the efficiency and serviceability of a heating furnace.

To accomplish the foregoing and other useful ends, my invention contains the means hereinafter more fully set forth and claimed.

Referring to the accompanying drawing, which is a top plan view, of the radiator ring for a furnace, the said'ring comprising a plurality of flues, A, B, and C, a clean-out opening K and an outletopening L, the three flues shown comprising the straight flue C and the branching flues A and B meeting at a common point in the rear of the radiator adjacent the chimney, the flue C leading directly to the combustion chamber and adapted to most directly convey the exhaust smoke and gases from the combustion chamber to the chimney, the other two flues A and B together being arc shaped and each forming a branching path, substantially similar in vertical section, from the fire box, about the circumference of the radiator to the chimney. i

In the direct flue C, I provide, a damper D pivotally supported on a shaft 03, for variably limiting the flow of exhaust gases through the flue C. p Carried on the shaft d, I mount a gear E. The flue C is connected to the combustion chamber located below T by a conduit M leading to the fire box, the conduit M and the damper D being shown in the drawing by dotted lines as these are located below the upper surface of the radiator ring flues.

Coincident with the central vertical axis of the furnace and the radiator, I have mounted a second gear F, which is pivoted on the outside of the shell of the radiator, to suitably mesh with the 'ot' a bolt and threaded to en a e gear E. It will be seen that by rotatingthe gear F, I can control the damper D. The mechanism for controlling the gear F consists of an arm 7, which. is: provided with a hole whereby the arm f may be pivoted at one end of the shaft G to the gear F, which shaft G is coincidentwith the centrally vertical axis of the furnace. .Onthisarm f, I. provide a pin 9, by means of which I can hold the arm f in any one of several sitions with respect to the gear F. '.Inasmuch as l provi'de a' series of holes 7b in a circle in the gear F, it will be seen, that I can fix the'arni. withrespect to the gear F, in any oneof several positions,'by changing the engagement of the pin 5 with any one ot the holes h. The pin may threads in the wheell or to engage threads in the holes ii. It will be understood, of course, that arm f is suitably pivoted to the shaft- G and held in position by any suitable device, such ,a nut or pin. T o the outer end of the arm, 7 ,1 pivotally attach a rod ll which extendsto the front of the furnace which is assumed to be at the right of the drawing, and from this position, the damper D can be regulLt6Cltl1TOllgliiLll medium otitherod ll.

It will be seen, therefore, that -regardless of the position of the horizontal axis of the radiator extending from left to right through the center G of the furnace, thelever H can be retained always in substantially the same position, with reference to the base of the furnace. This arrangement is important inasmuch as it enables the damper mechanism to be put in position at the factory, and when tlie riirnace is set up, the local conditions will notin any way attect, the operation of the daii'ipcr. The only thing necessary is to adjust the army with the pin 9 in the proper hole it, which will throw the lever H in the right position.

I might add with regard to the arrangement of locating the gear F centrally asexplained in the preceding that the arrangement is also advantageous inasmuch iit insures a standard, definite position for the handle of the damper located hand extremity of therod H. It also enables all oi": rods H to be cut 01 standard length and constructed cheaply.

It will be understood, of course,that the ring radiator Y. rests on top or the stove, which may be of the usual upright type, and that the central vertical axis of the radiator coincides with the central vertical, axis of the stove,,so that the gases pass from the fire bot; directly into the forward part ot the "central cross passage-way dividing thence into the branches A and B.

With reference to the means for interlocking the arm, f, with the gear wheel, F, this means involves the pin, .9, already referred to. it will be understood that the pin, 9, is

given pobe made in the form at the right 1 operated like any coupling pin, such action being so well known as it is thought unneces-' sary to describe the same in further detail.
